As batteries degrade, their capacity to store and deliver energy diminishes, resulting in reduced overall energy storage capabilities. This degradation translates into shorter operational lifespans for energy storage systems, requiring more frequent replacements or refurbishments, which escalates operational costs.
How to manage battery degradation?
Consideration of battery degradation depends on the organization of the power system. In regions with bilateral electricity markets such as Europe, storage owners have a wide degree of freedom to optimize market transactions, especially utilizing intra-day markets, 30 to manage battery degradation.
How does lithium ion battery degradation affect energy storage?
Figure 1. Degradation mechanism of lithium-ion battery . Battery degradation significantly impacts energy storage systems, compromising their efficiency and reliability over time . As batteries degrade, their capacity to store and deliver energy diminishes, resulting in reduced overall energy storage capabilities.
Are battery degradation models ready for bulk power system operations?
Although more sophisticated battery degradation models such as the cycle depth model, the SoE degradation model, and even some more complex nonlinear models are not ready for implementation in bulk power system operations due to computation complexity, the future may be different.
